With the worldwide spread of the novel severe acute respiratory syndrome coronavirus‐2 (SARS‐CoV‐2) resulting in declaration of a pandemic by the World Health Organization (WHO) on March 11, 2020, ...the SARS‐CoV‐2‐induced coronavirus disease‐19 (COVID‐19) has become one of the main challenges of our times. The high infection rate and the severe disease course led to major safety and social restriction measures worldwide. There is an urgent need of unbiased expert knowledge guiding the development of efficient treatment and prevention strategies. This report summarizes current immunological data on mechanisms associated with the SARS‐CoV‐2 infection and COVID‐19 development and progression to the most severe forms. We characterize the differences between adequate innate and adaptive immune response in mild disease and the deep immune dysfunction in the severe multiorgan disease. The similarities of the human immune response to SARS‐CoV‐2 and the SARS‐CoV and MERS‐CoV are underlined. We also summarize known and potential SARS‐CoV‐2 receptors on epithelial barriers, immune cells, endothelium and clinically involved organs such as lung, gut, kidney, cardiovascular, and neuronal system. Finally, we discuss the known and potential mechanisms underlying the involvement of comorbidities, gender, and age in development of COVID‐19. Consequently, we highlight the knowledge gaps and urgent research requirements to provide a quick roadmap for ongoing and needed COVID‐19 studies.
Severe acute respiratory syndrome coronavirus (SARS‐CoV)‐2, a novel coronavirus from the same family as SARS‐CoV and Middle East respiratory syndrome coronavirus, has spread worldwide leading the ...World Health Organization to declare a pandemic. The disease caused by SARS‐CoV‐2, coronavirus disease 2019 (COVID‐19), presents flu‐like symptoms which can become serious in high‐risk individuals. Here, we provide an overview of the known clinical features and treatment options for COVID‐19. We carried out a systematic literature search using the main online databases (PubMed, Google Scholar, MEDLINE, UpToDate, Embase and Web of Science) with the following keywords: ‘COVID‐19’, ‘2019‐nCoV’, ‘coronavirus’ and ‘SARS‐CoV‐2’. We included publications from 1 January 2019 to 3 April 2020 which focused on clinical features and treatments. We found that infection is transmitted from human to human and through contact with contaminated environmental surfaces. Hand hygiene is fundamental to prevent contamination. Wearing personal protective equipment is recommended in specific environments. The main symptoms of COVID‐19 are fever, cough, fatigue, slight dyspnoea, sore throat, headache, conjunctivitis and gastrointestinal issues. Real‐time PCR is used as a diagnostic tool using nasal swab, tracheal aspirate or bronchoalveolar lavage samples. Computed tomography findings are important for both diagnosis and follow‐up. To date, there is no evidence of any effective treatment for COVID‐19. The main therapies being used to treat the disease are antiviral drugs, chloroquine/hydroxychloroquine and respiratory therapy. In conclusion, although many therapies have been proposed, quarantine is the only intervention that appears to be effective in decreasing the contagion rate. Specifically designed randomized clinical trials are needed to determine the most appropriate evidence‐based treatment modality.
Objectives
To determine post‐COVID syndromes in the Indian population, correlating a wide spectrum of post‐COVID manifestations with acute disease severity and associated risk factors.
Background
...Post‐COVID Syndrome (PCS) is defined as signs and symptoms that develop during or after acute COVID‐19 infection.
Design of Study
This is a prospective observational cohort with repetitive measurements.
Methods
The study followed RT‐PCR confirmed COVID‐19‐positive survivors discharged from HAHC Hospital, New Delhi, for a period of 12 weeks. The patients were interviewed over the phone at 4 weeks and 12 weeks from the onset of symptoms for evaluation of clinical symptoms and health‐related quality of life parameters.
Results
A total of 200 patients completed the study. At the baseline, 50% of the patients were categorised as severe based on their acute infection assessment. At 12 weeks after symptom onset, fatigue (23.5%), hair loss (12.5%) and dyspnea (9%) were the main persistent symptoms. The incidence of hair loss (12.5%), memory loss (4.5%) and brain fog (5%) were found to be increased as compared to the acute infection period. Severity of the acute COVID infection behaved as an independent predictor for the development of PCS, with high odds of experiencing persistent cough (OR = 13.1), memory loss (OR = 5.2) and fatigue (OR = 3.3). Further, 30% of subjects in the severe group experienced statistically significant fatigue at 12 weeks (p < .05).
Conclusion
From the results of our study, it can be concluded that there is a huge disease burden of post‐COVID Syndrome (PCS). The PCS comprised multisystem symptoms ranging from serious complaints of dyspnea, memory loss and brain fog to non‐serious complaints of fatigue and hair loss. Severity of the acute COVID infection behaved as an independent predictor for the development of PCS. Our findings strongly recommend vaccination against COVID‐19, for protection from disease severity as well as prevention of PCS.
Relevance to Clinical Practice
The findings of our study support the multidisciplinary approach required for the management of PCS with a team comprising of physicians, nurses, physiotherapists and psychiatrists working in close coordination for the rehabilitation of these patients. As nurses are considered the most trusted professionals in the community and the class of health workers associated with rehabilitation, focus should be given to educating them on PCS, which would prove to be an important strategy for efficient monitoring and long‐term management of COVID‐19 survivors.
This study aimed to estimate the association between anxiety associated with COVID‐19 and somatic symptoms, using data from a large, representative sample (N = 2,025) of the UK adult population. ...Results showed that moderate to high levels of anxiety associated with COVID‐19 were significantly associated with general somatic symptoms and in particular with gastrointestinal and fatigue symptoms. This pattern of associations remained significant after controlling for generalized anxiety disorder (GAD), pre‐existing health problems, age, gender, and income. This is the first evidence that anxiety associated with COVID‐19 makes a unique contribution to somatization, above and beyond the effect of GAD.
The COVID‐19 outbreak has become one of the largest public health crises of our time. Governments have responded by implementing self‐isolation and physical distancing measures that have profoundly ...impacted daily life throughout the world. In this study, we aimed to investigate how people experience the activities, interactions, and settings of their lives during the pandemic. The sample (N = 604) was assessed in Ireland on the 25 March 2020, following the closure of schools and non‐essential businesses. We examined within‐person variance in emotional well‐being and how people spend their time. We found that while most time was spent in the home (74%), time spent outdoors (8%) was associated with markedly raised positive affect and reduced negative emotions. Exercising, going for walks, gardening, pursuing hobbies, and taking care of children were the activities associated with the greatest affective benefits. Home‐schooling children and obtaining information about COVID‐19 were ranked lowest of all activities in terms of emotional experience. These findings highlight activities that may play a protective role in relation to well‐being during the pandemic, the importance of setting limits for exposure to COVID‐19‐related media coverage, and the need for greater educational supports to facilitate home‐schooling during this challenging period.
Objective
Research on the psychological toll of the COVID‐19 pandemic is being conducted in various countries. This study aimed to examine risk factors for mental health problems among Israeli adults ...during this crisis.
Methods
A total of 204 participants took part in the study. They completed self‐report questionnaires assessing perceived stress, anxiety, quality of life, and various questions related to quarantine, pre‐existing health issues, and worries related to the virus. The study took place during the last two weeks of March 2020.
Results
The majority of participants reported relatively high levels of perceived stress and corona‐related worries, but low levels of anxiety. Female gender, younger age, corona‐related loneliness, and pre‐existing chronic illness were all related to higher levels of psychological distress and lower levels of quality of life.
Conclusions
While considering the preliminary nature of these results, the current study highlights risk factors for psychological distress in light of the corona pandemic. Attention should be given to sociodemographic variables that were identified as related to psychological distress, as well as to the important role of loneliness, when screening and treating people during this crisis. More research is needed in order to fully understand the scope and correlates of psychological difficulties during these challenging times.

It has been claimed that we are ‘all in it together’ and that the COVID-19 virus ‘does not discriminate’.
This accessible, yet authoritative book dispels this myth of COVID-19 as an ‘equal opportunity’ disease, by showing how the pandemic is a syndemic of disease and inequality.
Drawing on international data and accounts, it argues that the pandemic is unequal in three ways: it has killed unequally, been experienced unequally and will impoverish unequally.
These inequalities are a political choice: with governments effectively choosing who lives and who dies, we need to learn from COVID-19 quickly to prevent growing inequality and to reduce health inequalities in the future.
COVID-19 is an unequal pandemic.
